Plasmas are reactive ionised gases, which enable the creation of unique reaction fields. This allows plasmas to be widely used for a variety of chemical processes for materials, recycling among others. Because of the increase in urgency to find more sustainable methods of waste management, plasmas have been enthusiastically applied to recycling processes. This review presents recent developments of plasma technologies for recycling linked to economical models of circular economy and waste management hierarchies, exemplifying the thermal decomposition of organic components or substances, the recovery of inorganic materials like metals, the treatment of paper, wind turbine waste, and electronic waste. It is discovered that thermal plasmas are most applicable to thermal processes, whereas nonthermal plasmas are often applied in different contexts which utilise their chemical selectivity. Most applications of plasmas in recycling are successful, but there is room for advancements in applications. Additionally, further perspectives are discussed.

“…Simultaneously, the building ceramics industry has witnessed an increase in the consumption of raw materials, such as clay, quartz, feldspar, and quartz sand, to accommodate its expanding production capacity. However, recent studies have shown that utilizing low-cost industrial solid waste as substitutes for traditional raw materials or as additives to enhance the performance of ceramic materials can effectively alleviate resource scarcity issues and further mitigate the continuously increasing production costs [2][3][4][5][6]. It is noteworthy that, because of its substantial and expanding production capacity, the building ceramics industry has significant potential to mitigate the large-scale accumulation of solid waste [7].…”

Steel slag and waste clay bricks are two prevalent solid waste materials generated during industrial production. The complex chemical compositions of these materials present challenges to their utilization in conventional alumina silicate ceramics manufacturing. A new type of ceramic tile, which utilizes steel slag and waste clay brick as raw materials, has been successfully developed in order to effectively utilize these solid wastes. The optimal composition of the ceramic material was determined through orthogonal experimentation, during which the effects of the sample molding pressure, the soaking time, and the sintering temperature on the ceramic properties were studied. The results show that the optimal ceramic tile formula was 45% steel slag, 35% waste clay bricks, and 25% talc. The optimal process parameters for this composition included a molding pressure of 25 MPa, a sintering temperature of 1190 °C, and a soaking time of 60 min. The prepared ceramic tile samples had compositions in which solid waste accounted for more than 76% of the total material. Additionally, they possessed a modulus of rupture of more than 73.2 MPa and a corresponding water absorption rate of less than 0.05%.

In this article, we explore the sorption behavior of Zr(IV) ions by lithium titanate (LiTi), magnesium titanate (MgTi), and lithium magnesium titanate (LiMgTi) sorbents. These sorbents, fabricated using the precipitation method, were used for the Zr(IV) sorption from aqueous solutions. We employed various analytical tools, including XRD, FT-IR, BET, SEM, and EDX, to examine the prepared sorbents’ structure, morphology, and functional groups. We also studied the effect of pH, time, initial metal concentrations, temperature, and interfering species on sorption. The kinetic data obey pseudo-first-order. Many isotherm models were utilised to investigate equilibrium data. The results of thermodynamic functions show an endothermic and spontaneous sorption process. Finally, the influence of the interfering species reveals that as the concentration of CaCl2, MgCl2, and NaCl increases, the Zr(IV) adsorption rate decreases. The investigation demonstrated that LiMgTi is suitable for retaining Zr(IV) from aqueous solutions and could purify effluent polluted with Zr(IV) ions.
